The rate of people without health insurance in Massachusetts fell to a new low last year, according to a federal survey.
The report released Tuesday from the National Center for Health Statistics said 2.5 percent of people in the state were uninsured in 2015, down from 2.6 percent a year earlier. That is a historic low for Massachusetts, federal officials said.
Nationally, the rate of people without health insurance was 9.1 percent, down from 11.5 percent, which marked the first time fewer than 1 in 10 Americans lacked health insurance, officials said. The Obama administration credited that figure to the Affordable Care Act, also known as Obamacare. The law mandated insurance coverage and expanded insurance to people who were previously uncovered.
Massachusetts law also requires residents to obtain health insurance. The state adopted a health care overhaul in 2006.
Another recent survey from the state’s Center for Health Information and Analysis estimated that 3.6 percent of people in Massachusetts lacked health insurance. That is still among the lowest rates in the country.
“All studies confirm that Massachusetts has the lowest level of uninsurance in the country,” Brian Rosman, research director at the consumer advocacy group Health Care For All, said in an email. “The results are a testament to our strong policies that make affordable coverage available to people, and to the extensive network of navigators and assistors who work in hospitals, community health centers, community groups, and other sites to get people enrolled.”
The federal survey said 36 percent of Massachusetts residents were covered by taxpayer-funded insurance programs, such as Medicare and Medicaid.
